I have one of these for sale - worked perfect before i took it out.
The Spec R features a dual solenoid that diverts pressure away from the turbo actuator to achieve higher boost. This dual solenoid is linked to a smart control unit installed inside the car, which allows you to control the boost pressure.
The control unit also displays live boost pressure.
The Spec R unit has four user programmable boost settings.
Scramble and gain settings are programmeable.
There is a boost warning mode, which can be pre set to visually and audibly alert the driver to an overboost situation.
The unit can also be programmed to reduce the solenoid duty cycle in an overboost situation.
It is suitable for both internal and external wastegate applications.
The Spec R can control up to 2.5 bar of boost, and is supplied with wiring and English instructions.
